Which practice can reduce the risk of radiation exposure during imaging?

Employing the ALARA principle, which stands for "As Low As Reasonably Achievable," is a fundamental practice in radiation safety aimed at minimizing radiation exposure to both patients and healthcare personnel. This principle encourages the careful consideration of radiation dose levels, ensuring that any medical imaging procedures involving radiation are justified and that the doses are kept as low as possible without compromising the quality of the diagnostic information.

By implementing the ALARA principle, practitioners actively assess the necessity of imaging studies, utilize techniques and technologies that lower exposure, and apply protective measures effectively. This approach not only fosters a safer environment in medical settings but also promotes awareness and responsibility regarding radiation use, making it a key practice in radiation safety during imaging procedures.

In contrast, increasing exposure time, using a high mA setting, and employing fewer collimation techniques would increase the amount of radiation received, leading to higher exposure risks, therefore not aligning with the goals of effective radiation safety practices.
